The Werma 645.890.60 is an industrial-grade 8-tone siren module tailored for use in Werma’s KombiSIGN 71 and 72 modular signal tower systems. Operating on a wide 115–230 VAC input, it provides a powerful and reliable acoustic signal that reaches up to 102 dB (A) at 1 meter—ideal for noisy manufacturing and process environments. Users can easily select one of eight predefined alarm tones using built-in DIP switches, allowing tone customization to match various machine states, safety alerts, or process warnings. The volume level is also adjustable (approx. 92–102 dB) via an internal selector switch. Housed in a compact black enclosure with an IP65 protection rating, this siren module is resistant to dust and water jets, making it suitable for demanding indoor and outdoor applications. Its robust construction, clear acoustic output, and compatibility with KombiSIGN towers make it an ideal component for any AC-powered industrial signaling system.
